Additional Information and Online Ordering

Pierce Streptavidin Agarose and UltraLink Resins supply immobilized streptavidin biotin-binding protein in different resin formats, binding capacities and package sizes to suit nearly any immunoprecipitation or affinity purification procedure involving biotinylated molecules. The products use a recombinant form of streptavidin with a mass of 53 kDa and a near-neutral pI. The resins are prepared by covalently coupling streptavidin to the porous agarose or UltraLink Biosupport using efficient and stable chemistries, resulting in Streptavidin Agarose and UltraLink Resins that are leach-resistant and stable at pH 2-11. The products are excellent choices for a variety of small- or large-scale affinity purification applications involving biotinylated macromolecules, including separation of biotinylated molecules from samples and immunoprecipitation of antigens using biotin-labeled antibodies.

Highlights:

• Proven coupling chemistries – the methods used to prepare these resins are superior to typical cyanogen bromide (CNBr) immobilization, providing high functionality, low nonspecific binding and excellent leach-resistance

• Versatile resins – Agarose (polysaccharide-based) and UltraLink™ Biosupport (acrylamide-based) resins provide two different options for particular experimental conditions and are compatible with gravity-flow, spin and FPLC methods

• Available in multiple formats – choose from two resin types, regular or high capacity preparations, and small or large-scale package sizes (bulk sizes are also available)

• Superior performance – High Capacity Resin has 2 to 3 times higher binding capacity than alternative supplier products, allowing use of small amounts of resin for experiments

Item-Specific Features:

• Agarose Resins are crosslinked 6% beaded agarose
• UltraLink Resins beaded acrylamide support (UltraLink Biosupport)
• Plus and High Capacity Resins have higher loading (i.e. density) of immobilized streptavidin protein than the regular forms
